Changing an Atlas assigned to a UISprite?

[ENAY]

How do I do this?

So far I have assigning new sprites in an atlas. Using something like this:-

mySprite.spriteName = "other_sprite_name";

This all works but now I want to do something like this.
mySprite.atlasName = "other_atlas_name";

I have searched around on this forum and found .replacement

But I can't seem to get it to work. I have loaded two atlases like this:-

UIAtlas myAtlas1 = Resources.Load("mydir/myAtlas1", typeof(UIAtlas)) as UIAtlas;
UIAtlas myAtlas2 = Resources.Load("mydir/myAtlas2", typeof(UIAtlas)) as UIAtlas;

Then I call my atlas change.

mySprite.atlas.replacement = myAtlas2;


However if I debug the atlas (mySprite.atlas), it is still pointing to myAtlas1.

Am I missing something obvious?

Ok, fixed it now. That is a weird one.

Seems all I needed was

mySprite.atlas = myAtlas2;

Not sure what replacement does but it didn't seem to do anything for me.

Replacement atlas feature is used for atlas swapping on mobile platforms when you need SD / HD / UD atlases. There is a video tutorial on how to use it.

Aah, that would make sense. I searched and found that video tutorial. Thanks for that
